While driving my traverse my traction control will turn off, service stabilitrak will come on and it will say engine power reduced and will slowly start to slow down. If you come to a complete stop and try to hit the gas again it will shake and kind of studder. This has happened both on a city street and on the highway. The city street was on a curvy road and the highway was a straightaway. This…

What stands out
Owners have filed 48 electrical complaints with NHTSA against this vehicle, but no formal recall covers the issue — the federal record reflects what manufacturers have admitted, not everything owners are reporting.
No new NHTSA electrical complaint has been filed on this vehicle in over 8 years — the issue may be aging out of the active population.
The failure pattern owners describe
Buyer takeaway: The 2011 Traverse has a well-documented pattern of serious electrical and computer-related failures—from alternator collapse to mysterious power loss and stalling—that occur repeatedly even after repair and can disable the vehicle on the highway. Multiple owners report spending thousands on diagnostics and repairs that don't fix the problem, while safety features (steering, braking, stability control) sometimes fail without warning.
Owners of 2011 Traverses describe a car plagued by electrical gremlins that range from annoying to genuinely dangerous. The most critical issue: alternators fail within a year of replacement, causing the battery voltage to tank mid-highway drive and the engine to stall. When it happens at 65 mph, owners lose power steering and can't stop the vehicle safely.
Power loss and stalling are endemic complaints. Owners report the "Engine Power Reduced" warning slamming them from 70 mph down to 5–10 mph in seconds, sometimes from a complete stop. This isn't a gradual limp—it's violent, and it happens on freeways in heavy traffic. The root causes dealers identify are inconsistent: bad coils, throttle body electrical faults, and mysterious short circuits. Repairs don't stick; the same failure recurs.
Secondary electrical systems fail early. Window regulators stop raising or lowering. Wipers fail. Speakers cut out in cold or wet weather, killing safety alerts (backup warnings, seat belt chimes). The door locks cycle uncontrollably while driving. Dashboard gauges and climate controls freeze up mid-drive, then restart.
Water intrusion appears widespread. It pools in the battery compartment, corrodes the fuse box, and grows black mold in the carpet, causing health issues. Dealers can't locate the leak source even after a week of work. Headlights have caught fire at the wiring connection. One owner smelled burning wires, lost steering and braking, and nearly hit a bridge pillar before the engine died entirely.
Some of these failures are out of warranty quickly. Owners face $3,500–$5,000+ repair bills for problems they can't diagnose themselves and dealers can't fix reliably.

Failure modes owners describe
Intermittent stalling and no-start / key recognition failure
Vehicle experiences sudden loss of power and stalling while driving or won't start after parking. Dashboard warning lights flash or illuminate, radio loses power, and power steering cuts out. Key is not recognized by the vehicle computer. Incidents occur intermittently and may resolve after sitting idle or restarting.
When: Occurs both while driving and at rest; can happen within minutes of previous incident or weeks apart
Symptoms owners cite: Engine stalls without warning while driving; Vehicle won't start; key not recognized by computer; Dashboard warning lights flash/illuminate during incident; Radio loses power during event; Power steering loss; Vehicle starts normally again after sitting idle or restarting multiple times
Repairs/costs cited: Mechanic unable to diagnose root cause after $438 diagnostic; incidents often resolve on their own. One owner reported opening trunk and retrying start as temporary workaround.
Alternator failure and repeated charging system collapse
Alternator fails prematurely, allowing battery voltage to drop below safe levels while driving. Battery dips periodically from 14V to 12V or lower. Replacement alternators fail again within 6-10 months, creating a recurring pattern. Vehicle stalls with warning lights illuminating simultaneously.
When: First failure less than 1 year after purchase; second failure 10 months after initial replacement
Symptoms owners cite: Battery voltage gauge drops below 14V to 12V while driving; All warning lights illuminate simultaneously (check engine, stabilitrak, battery); Vehicle stalls mid-drive on highway at 50+ mph; Voltage dipping occurs about 20 minutes into drive; Engine compartment overheating/components fried
Repairs/costs cited: Alternator replaced; battery replaced; AC components and wiring fried by electrical surge. Second alternator replacement performed 10 months later. Costs not specified beyond initial replacement.
Ignition coil failure causing engine power reduction and limp mode
Engine misfires and loses power when coils fail. Vehicle enters reduced power mode, slowing dramatically from normal highway speed to crawl. Service Stabilitrak, Traction Control, and Engine Power Reduced warnings illuminate. Coils fail in groups (4 out of 6 reported) or individually over time.
When: First incident during hilly backroad drive; second incident on I-95 at 65 mph; occurred 8 times in succession before reaching dealership
Symptoms owners cite: Service Stabilitrak and Traction Control warnings; Engine Power Reduced warning; Sudden loss of engine power; Vehicle slows to 10-20 mph without driver input; Hard steering during limp mode; Misfire/rough running; Multiple occurrences in single trip (8 times in one incident)
